Recreating the smell of rain (Petrichor) with geosmin

[@Kalembastudioart]

Not sure where to post this, however I think it is an interesting observation by myself. I noticed that a 50% blend of Jasmine and cedar smells similar to freshly cut grass! So, after watching this amazing video I realized that in the formula you gave today, if you added Jasmine and Cedar, even in a minute amount this may help with the smell of what this video explains! I could be wrong though. If you try a couple of drops of each cedar and jasmine, you will understand where my thought process comes from!

[@sammacer]

Oh cool! Guessing it’s jasmine sambac since that’s quite green to me. I imagine adding those would make it smell like a rain next to jasmine flowers in a cedar forest. Have you smelled cis-3-hexenol? I wonder how your accord compares to that since it’s the canonical cut grass smell.

[@Kalembastudioart]

@@sammacer Never tried cis-3-hexenol but will look into it!

[@waqarghulam3548]

You are correct. But the smell of rain on dry parched earth is not the same as fresh cut hay. Mitti atar that Sam talked about is a beautiful top note for creating fresh scents

[@michaelcorbridge1607]

If I could give an award for the greatest ever informative video ever made, I would award it to this amazing video. I cannot thank you enough.

[@simonstergaard]

Its the taste of catfish...muddy when eaten. As an organic chemist i really like that you do a deep dive. I think there is an article that found that geosmin is made by a specific type of bacteria when it is dry, and that geosmin prevent seeds to sprout, which is quite useful, as you dont want to sprout when it dry... nature i epic.

[@sammacer]

That’s really cool, shame that I missed it!

[@justaddlight]

Very interesting about the fractal dynamics of raindrops hitting a surface. It's one of the reasons I love walking in a cool forest hours after a thunderstorm. The residual water falling off of the foliage after having absorbed many of the surface particles creates a wonderful stratified bubble all the way up to the canopy. 🌳 A fabulous vid Sam. Too right about those strong sulphurs. Really gotta dilute those down.

[@sammacer]

Thank you!

[@tomask9588]

Sam's videos are great in general, but this particular one is so good I have to write a comment. Thank you, sir. I've been a perfumery lurker for months, but your vids motivate me to take the scentless theory into the fragrant practice.

[@sammacer]

Fantastic to hear, good luck with your perfumery, let me know how it goes 😊

[@siyaneliswashozi6384]

This is brilliant I have always wanted to see if you can recreate the smell of rain. I think you could possibly add a mossy/oakmoss nature to the accord and see how it does? Anyway brilliant idea

[@sammacer]

Thank you! And yes, that sounds like a good Avenue for exploration

[@NatureNotesByKaki]

Wow, Sam - I was absolutely mesmerized by this video!!! I randomly (and very fortunately!) stumbled across it when I was just generally looking into petrichor. Thank you so much for this incredibly informative and intriguing experience!

[@sammacer]

Thank you, im glad you found it interesting :)

[@superodfx]

I love the smell of rain hiking here in an Australian eucalyptus bush forest, perhaps closer to the terpene high accord you chanced

[@sammacer]

The sounds lovely - you could add some eucalyptus essential oil to the accord and probably get that effect :)

[@curioclassicperfumeguide]

I am not a perfumer, I am a perfume lover just like you. I was very curious about the fragrances and being watched videos, read books and articles , Indian and Western. Now I am sharing videos of fragrances formulation .

[@russellmoxham5625]

Fascinating, thank you. I'm no perfumer and don't have any real technical grasp of how different woody aromatics play off against one another or whatever, but I'd be tempted to try combining this with Evernyl and/or something akin to dirty vetiver. That cedar idea also sounds appealing, partly for some of the same reasons as patchouli (whether it would actually work or not). One of my all-time favourite designer fragrances is the discontinued Bvlgari PH Soir. It probably smells quite synthetic and strident but it takes quite a minimalist approach, with just a few notes/accords listed. There's just tea, papyrus, musk and amber, I think. The tea is very green and ozonic. (I usually find tea notes and violet leaf notes quite similar.) The papyrus is very much like a dark, damp, earthy vetiver, with definite musty library vibes. To my nose, the overall effect is quite reminiscent of petrichor, although the amber in particular points in another direction. I've yet to get my hands on another fragrance that gives me such an instant hit of rainy dirt or dirty rain. I am working on it. I suspect that that hallowed grey Narciso Rodriguez fragrance would have delighted me. Next stop, Peau d'Ailleurs.

[@jori7398]

Morning Sam! 20:36 really appreciated your thoughtful insight that the addition of patchouli would make the fragrance specific to a certain region. Awesomeness! 🌧️ 🩵 💙

[@sammacer]

Hopefully this one works for you

[@Thuja814]

Great video! I’m working on a rain-y fragrance, myself, rather than a rain accord. I imagine walking next to Lake Ontario, downtown Toronto, while it’s still misting after a heavy rain… For a real niche frag, one might include car exhaust and the overflow ducts of a sewage treatment plant. Clearwood & patchoulol are helpful substitutes for patchouli here. In addition to Floralozone (which I do not have), Helional and Cascalone are interesting. I don’t like the cis-3-hexenol either, it ruined a trial, but seaweed absolute is fabulous and I’m eyeing the galbanum resin. Your mention of myrcene, pinene & terpineol lead me to the lovely wild juniper berry oil (thank you!) while acknowledging the cypresses & pine. Cedrat coeur made an appearance, and it smells like the clouds might part. Also considering amyl salicylate, a metallic watery clover? Mandarin petitgrain?! Orris butter? B-caryophyllene? 🤷

[@Thuja814]

Humus ether?!? 😛

[@jrosin12]

Hey Sam, did you use the dimethyl sulfide at 1%?

[@sgargabonzo]

I made a rainy accord using: basil, calone, vetiver, patchouli, cedar wood and mousse de metre. It s very good

[@sammacer]

[@eestiny9734]

Petrichor straight up smells like by the river rocks nothing like rain on my nose (tried to have it grow on me cause i love rain, but style can't). And the smell isn't that pleasant. The smell of rain depends also on the geography (rain is a bouquet of both from the air and anything on the ground , and the nature of the surface the rain is falling on! Have been disappointed by countless fragrances that tried to capture rain, petrichor or not... same with fragrance that "smells" like the sea.

[@chrisjensen9721]

Desert rain is sumptuous, especially in Arizona and New Mexico. The smells are stronger if it's been really hot

[@ignisignisandrek]

I am a perfumer. And I want to make real smell of a fresh cucumber with violet. But no violeaf, nor cucumber absolute itself, doesn't give the smell I want

[@Suciu_Andrei_Lucian]

You can create a violet acord by using alpha and beta ionones Calone has a seabrease or melon smell, so that can be used to create a cucumber smell

[@CraigersPvtchef]

Amazing video!!!!

[@JamieBarnes11]

Great video. I've actually just started working on a damp earth accord myself so there's a bit of crossover here for sure. Have you ever tried Earthy Pyrazine at all? Ive been mixing that with Geosmin and Terrasol and I think it's great for that damp earth feeling. What i will say though is that it's really insanely stong. Like, combined geosmin at 1% dilution, terrasol at 1% dilution and Earthy Pyrazine at 0.1% dilution in equal proportions it still basically makes the accord smell entirely like potatoes. It's really that strong. So you need really the tiniest trace of it. Also just talking terpenes in general: have you tried Vetiver Terpenes? I just got some recently and it seems like it could be a pretty useful matieral for a number of things.

[@sammacer]

I tried earthy pyrazine when planning the accord but in my eyes it didn’t fit. I don’t have vetiver terpenes!

[@Peem_pom]

I actually do have access to it, here in India so I'm going to check that out!

[@sammacer]

No problem, it’s good that people have access to information. Yes, I used to have two others, but I don’t like them anymore. I really spend a long time trying to perfect my perfumes and I’m also very busy so it’s not very often that I get to release one. I’m releasing a new one in a couple of weeks and working on a few more for next year!

[@ms.s.vincent]

I'm a newbie and I only recently discovered your channel, so I could be completely wrong, but after smelling Molecule 05 from Escentric Molecules (cashmeran) I feel like it would be a great ingredient for recreating this elusive scent. To me it smells a bit of dirt/concrete with a bit of greenness somewhere. If you ever try it let us know :D

[@sammacer]

Yes I completely agree cashmeran smells earthy - but not as much as the molecules here. If you wanted to make the accord less realistic and more perfumey then I would definetly consider cashmeran

[@ms.s.vincent]

[@takky4774]

Take the mic sensitivity down a bit. Its noisey

[@multiz0rak]

iirc christopher brosius of i hate perfume did something along these lines a while ago, and it was quite camforous. so maybe it's an option to try pure camphor instead of patchouli. also it's strange that cashmeran wasn't even mentioned, i would think it's a natural candidate for an earthy-rainy smell. also it would be fun to play with eucalyptus/mint kind of materials that have the trigeminal cooling effect on the nose

[@sammacer]

I did think about cashmeran, camphor and mint. I find cashmeran not as earthy as pure geosmin or even something like terranol. Camphor seemed like it wouldn’t be present in most rain and the same with mint. Certainly logical avenues of exploration though!

[@multiz0rak]

@@sammacer regarding camphor and mint: i guess in the end it depends on the level of abstraction you're aiming at. whether it's a photorealistic headspace sort of smell of wet soil or an artistic evocation of rain in a perfume. obviously in the latter case you have an artistic license to use whichever material you want :)

[@sammacer]

Hello Sam! Great video, may i ask you why you decided to work with your materials pre-diluted to 1% instead of the classic 10%?

[@sammacer]

Thanks! In this case most of the raw materials are very strong and so 10% is completely overwhelming. For the terpenes, they are meant to be in the background, not the core smell, which is why they are low.

Is the Patchouli from the Patchouli plant or did you get a synthesized molecule? Are chemists already synthesizing all natural essences? I noticed that strawberry synthetic molecules actually have the same skin healing effects.

I wonder, what would terranol do to that accord?

[@sammacer]

I looked at terranol for this video but didn’t have time to cover it. In my opinion it’s like “geosmin made more elegant for perfumery” - so maybe in a real perfume switching geosmin for terranol would be a good modification

[@srgttamtam]

@@sammacer Right. Actually, I had interesting results, combining terranol and geosmin in a 6:1 ratio. Give that a go, if you obtain some geosmin. Might also be interesting to play around with some Musks, especially the animalic ones like f.e. exaltone or exaltolide. That doesn't necessarily make it smell like rain, but it kind of adds to the ground part of the accord.
